A report was published in 2011 by the World Energy Council in association with Oliver Wyman, entitled Policies for the future: 2011 Assessment of country energy and climate policies, which ranks country performance according to an energy sustainability index. The best performers were Switzerland, Sweden, and France.
Piper Jaffray expected strong growth in France in 2009 and 2010, partly because of an expected decline in the price of solar panels and partly because of subsidies introduced in 2006 making themselves felt. France should be a key driver for solar together with Italy during 2009-2010. Piper Jaffray believes that France would add 500 megawatts of capacity in both 2009 and 2010. France has 50 megawatts of solar power capacity now.
In July 2015, the French parliament passed a comprehensive energy and climate law that includes a mandatory renewable energy target requiring 40% of national electricity production to come from renewable sources by 2030. For context, 19.5% of the country's electricity was generated by renewable energy in 2014 (13.8% hydro, 3.5% wind, 1.2% solar, 1.0% others).
